What is sulfur alloy cored wire

Sulfur alloy cored wire A core tube made of steel tape and filled with sulfur core. It is helpful to adjust and control the sulfur content in liquid steel or liquid iron, and it is convenient to obtain steel or iron products with appropriate sulfur content. Adding sulfur to liquid iron and liquid steel is conducive to improving the machinability of finished steel and iron products and facilitating the subsequent processing and production. Sulphur-containing alloy core-wire is made of steel strip coated with sulphur powder or pyrite powder. The sulfur powder and pyrite powder contain water, the content of water < 0.5%, S > 99.5%. The sulfur-containing free-cutting steel has very high requirements for H element, so the moisture requirements for raw materials are relatively strict. When the water in the sulfur-containing core wire is fed into the liquid steel, hydrogen will produce hydrogen, which will cause bubbles and pinholes on the surface of the product in the liquid steel, affecting the material of the sulfur-containing free-cutting steel, so when the sulfur core wire is fed, argon should be blown at the bottom and mechanically transported, and the cost can be reduced. Advantages:
1. Add sulfur to molten steel with sulfur alloy cored wire to produce sulfur-containing free-cutting steel; The recovery rate of sulfur can reach more than 80%.

2. Add sulfur to stainless steel molten steel with sulfur alloy cored wire to change the appearance of vulcanized inclusions and improve processability.
